MIBA-US is the regional network of the global MIBA network organized by the International Atomic Energy Agency . It aims to install a global network of ¹⁸O in moisture samples from leaves, stem, soil (and water vapor) at existing ecosystem flux sites to complement the Global Network of Isotopes in Precipitation and to integrate isotope applications in hydrological cycle, carbon cycle and climate research.

• Regional scale hydrological budgets
• The partitioning of annual carbon fluxes
• The development of new global change indicators
• Ecosystem functioning


• Interpretations of ¹³C and ¹⁸O analyses in organic matter
• The validation of general circulation models
